Video 6. Supraorbital vibrissa movement persists after buccal but not temporal/zygomatic nerve cut.
Raw video (slowed 20-fold) showing split-screen view of mouse whiskers (A1 and A2) and supraorbital (SO) vibrissae on the left side, and whiskers (C-row) on the right side, during whisking. The left A1 whisker (black overlay), left caudal SO vibrissa (blue overlay), and right γ or C1 whisker (black overlay) are tracked. The angular positions of the whiskers (θL and θR, black traces) and SO vibrissae (θSO, blue trace) are shown at bottom. The first episode shows that the SO vibrissae whisk in phase with the ipsilateral whiskers prior to nerve cut. The second episode occurs after cut of the left buccal branch of the facial nerve. Whisking of the left whiskers is abolished, but the SO vibrissae continue to whisk. The third episode occurs after subsequent cut of the left facial motor nerve at the junction of the temporal and zygomatic branches (Figure 4—figure supplement 1G). SO vibrissae whisking is abolished.
